Disclosed is a method for detecting a frequency offset in an Orthogonal Frequency Division Multiplexing (OFDM) system. The method includes determining a first frequency index based on autocorrelation values calculated according to a frequency index for a pilot signal of a received symbol, accumulating the autocorrelation values calculated according to the frequency index for the pilot signal of the received symbol depending on a symbol count, and determining a second frequency index based on the accumulated autocorrelation values, and determining at least one of the first frequency index and the second frequency as a frequency offset according to channel quality.
